Galvanizing line upgrading at Ternium USA

Ternium USA contracted Danieli Service to supply two, new payoff reel mandrels complete with outboard bearings for the galvanizing line in operation at Shreveport works, Louisiana.

The design of the new mandrels will be “high-expansion type” in order to unwind coils with both 508-mm and 610-mm internal diameters without the need of any adapter.

The implementation of the solution proposed by Danieli Service will allow Ternium Shreveport to improve safety by eliminating the high-risk activity from operators manually installing rubber inserts into 610-mm ID coils, aligning with Ternium Safety Goals and moving forward to Industry 4.0.

Additionally, this will provide scheduling flexibility to switch between 610- and 508-mm ID coils, eliminating this task and allowing the operators to focus on other tasks that are more productive.

New hydraulic outboard bearings mounted on operator side to avoid mandrel deflection due to coil weight and strip tension will also be supplied, along with a new hydraulic system.

The installation of the new equipment is foreseen during a scheduled plant maintenance stop in 2026.
